Based on the tradition of the United Nations, Parties are organized into five regional groups:

African States,

Asian States,

Eastern European States,

Latin American and the Caribbean States, and

Western European and Other States.

But substantive interests of Parties and several other groupings are more important for climate
negotiations. The major groupings, for substantive and political purposes, are:

Group of 77 and China (G-77 and China) Developing countries generally
work through the Group of 77 to establish common negotiating positions. The G-77 was founded in 1964 in the
context of the UN Conference on Trade and Development (UNCTAD) and now functions throughout the UN system. It
has over 130 members. The country holding the Chair of the G-77 in New York (which rotates every year) often
speaks for the G-77 and China as a whole. However, because the G-77 and China is a diverse group with differing
interests on climate change issues, individual developing countries and groups within the G-77 also intervene
in debates.

Alliance of Small Island States (AOSIS) A coalition of some 43
low-lying and small island countries, most of which are members of the G-77, that are particularly vulnerable
to sea-level rise. AOSIS countries are united by the threat that climate change poses to their survival and
frequently adopt a common stance in negotiations.

Least Developed Countries (LDC) The 50 countries defined as Least
Developed Countries by the UN regularly work together in the wider UN system. They have become increasingly
active in the climate change process, often working together to defend their particular interests, for example
with regard to vulnerability and adaptation to climate change.

European Union (EU) The 27 members of the European Union meet in
private to agree on common negotiating positions. The country that holds the EU Presidency - a position that
rotates every six months - then speaks for the European Union and its 27 member states. As a regional economic
integration organization, the European Union itself can be, and is, a Party to the Convention, but it does not
have a separate vote from its members.

The Umbrella Group A loose coalition of non-EU developed countries
which formed following the adoption of the Kyoto Protocol. There is no formal list, but the Group is usually
made up of Australia, Canada, Iceland, Japan, New Zealand, Norway, the Russian Federation, Ukraine and the US.
The Umbrella Group evolved from the JUSSCANNZ (an acronym for Japan, the USA, Switzerland, Canada, Australia,
Norway and New Zealand) group, which was active during the Kyoto Protocol negotiations.

Environmental Integrity Group (EIG) Formed in 2000, the EIG comprises
Mexico, the Republic of Korea and Switzerland.

Other groups in the climate change process include the Organization of
Petroleum Exporting Countries (OPEC), Central Asia, Caucasus, Albania
and Moldova (CACAM), the League of Arab States and the
Agence intergouvernementale de la francophonie.
